This Air Force Manual (AFMAN) implements Air Force Policy Directive (AFPD) 23-1, Materiel
Management, using the Spares Requirement Review Board (SRRB) as the process to forecast
depot level reparable and United States Air Force (USAF)-managed spares requirements for
Program Objective Memorandum (POM) submission. This manual applies to all civilian
employees and uniformed members of the Regular Air Force, AF Reserve, and Air National Guard.
This publication does not apply to the United States Space Force. This manual may be
supplemented at any level, but all supplements that directly implement this publication must be
routed to the AF Weapon System Sustainment Division (AF/A4PY) for coordination prior to
certification and approval. Refer recommended changes and questions about this publication using
the DAF Form 847, Recommendation for Change of Publication; route DAF Form 847 from the
field through the appropriate functional chain of command. The authorities to waive wing-/unit-
